S. a Palaeobotanical Society was founded at Lucknow in May 1946 and registered under the Societies Rt:ginration Act (XXI of 1860) in June 1946. By a resolution passed on 10th September 1946 the Gove, ning Body of the Palaeobotanical Society established an Institute of Palaeobotany and appointed Professor Sahni as its first Director in an honorary capacity. Pending the acquisition of a permanent home the work of the Institute was carried on in the Department of Botany at the University of Lucknow. In September 1948 the Institute received from the Government of Uttar Pradesh the generous gift of an estate comprising a large bungalow on 3t acres of land at 53 University Road, Lucknow. Soon plans were made for erecting a lIew modeIt'n building for the Institute. On 3rd April 1949 its foundation 5tolle w 1S laid by Pandit Jawaharlal N hru who. besides being the Prime Minister of India, was at that time also the Minister of Scientific Research and Natural Resources. Wi,hin a week of this ceremony the young Institute suffered an irreparable Joss in the sudden and untimely passing away of its Founder Director, Professor Birbal Sahni. The most apt tribute was paid to him when in OCLOber 19-!-9 the Governing Body of the Palaeobotanical Society named the Institute after him as the Birbal Sahni Institute of Palaeobotany. Subsequent to Professor Sahni's sudden passing away, on 11th April 1949 the Govrrning Body of the Palaeobotanical Society au tho• rised his wife, Mrs. Savitri Sahni, to discharge all the duties of the Director of the {nstitu'e in addition to her own duties as the President of the Society. In May 1950 Dr. R. V. Sitholey. Assistant Director was appointed as Officer-in-charge for carrying out the current duties of the Director under the supervIsIon of the Presiden t. In 1951 the United Nations Educational, Scientific and Cultural Organization (UNESCO) included the Institute in its Technical Assistance Pro• gramme, under which Professor O. A. H¢eg of the University of Oslo, Norway, served as its Director from October 1951 to the beginning of August 1953. A short time after Professor H¢eg's departure, Dr. K. R. Surange was made the Officer-in-charge under the supervision of the President, Governing Body of the Palaeobotanical Society. In October 1959 Mrs. Savitri Sahni, in addition to being the President of the Society also became the President of the Institute and was incharge of the administration. At the same time Dr. Surange was appointed as Director having charge of academic and research activities. At the end of 1967 it was felt that a stage had come when the Pal• aeobotanical Society should function purely as a professional scientific body and Institute as a separate institution. A new constitution was framed under which the Birbal Sahni 1nstitute of Palaeobotany was re• gistered as a separate body on 9th July 1969. In November 1969 the Palaebotanial Society transferred and delivered possession of the Insti• tute to this new body whereby the 13irbal Sahni Institute of Palaeobo• tany came under the management of a new Governing Body with Professor T. S. Sadasivan of the University of Madras as its Chairman. The present report pertains to the year the Institute started as an independent institution and covers its activities from April 1969 to March 1970. II. RESEARCH 1. PRE-GONDWANA 1.1 Microfossils from Rampura .•. Leio,phaeridia, Pr%leiosphaeridium, Retisph, ridium, 7asmaniles and an algal remain Gloeocapsomorpha were recorded belonging to the Kaimur Series (Vindhyans) Madhya Pradesh. Age of the Vindhyans h<ls been discussed in the light of these discoveries. 2 1.2 Devonian sporeS A rich assemblage of Acritarchs and spores has been recorded for the first time from palynological samples ranging from Silurian to Devonian deposits. 2. LOWER GONDWANAS 2.1 Glossopteris flora-morphological and stratigraphical studies. 2.1.1 Mahanadi Valley Handappa, Orissa Some new male and female fructifications referable to the Glos• sopteridales have been recorded. The male fructifications are Glossotheca utkalensis gen. et sp. nov., Eretmonia utkalensis sp. nov., E. hinjridaensis sp. novo and E. karanpurensis sp. novo In Glossotheca naked sporangia in aggregates are borne on ultimate branch!ets and six of the aggregates are carried on a common pedicel attached to the stalk of a fertile leaf. In all the three species of Eretmonia the sporangial clusters are only two in number. The female fructification Lidgeltonia indica carried stalked, naked ovules on 'he futile leaf stalk. Morphology of female fructifica• tions Scutum and Cistella is explained Scutum is a compact cone, with ovules carried on a small, thin scale leaves. In Cistella the ovules are devoid of scales and they are perhaps embedded on a mulbery like fleshy head of the cone. It is concluded that southern hemisphere Glossopteridales is a group of extinct gymnosperms; although showing remote relationship with Pteridosperms, distinct enough to stand on its own as a separate group. The variety of reproductive organs show that in Glossopteridales we are perhaps dealing with more than one order. 2.1.2 South Karanpura Four species of Gangamopteris and some species of Glossopteris have been recorded from a shale bed about 70 feet above Argada (S' Seam. The dominance of Gangamopteris indicates the Karharbari age. Twelve species of Glossopteris, out of which three are new, have been described 3 from tbe sbales of Argada Seam, Lower Nakkari Seam and Upper Nakkari Seam. Glossopteris fusa sp. novo is di~tinguished by the evanescent nature of midrib and closely spaced elongate meshes of equal size. G. pftiolala sp. novo is distinguished 1::y a petiolate lec.f and closely spactci, more or le"s straight secondary veins which form narrow palygonal meshes. G. haranpurensis sp. novo is distinguished by its large sizE', arched secondary veim which run straight to the margin and form open hexagonal meshes of equal size. The study of a large number of impressions of Sphellopter;'s fronds from the farakar stage reveals that Sphenopteris pol)"morpho Feistrn.) 1881 and S. hlighesi Arher, 1905 are homonyms. S. poi.Jmorpha is emended and retained on the basis of nomenclatural priority. 2.1.3 Rajmahal Hills Some megafossils from the Bansloi valley have been recorded from localities mapped by BaJJ as ,be Dubrajpurs. Tbe Dubrajpur group had earlier been either included in the Lower Gondwanas or equated with the ?\lahadevas. Sandstone and shale beds overlying the Lower Gondwana and referred to as the Dubrajpur have yielded plant f('lssils characteristic of the RajrndhaI Intertrappean Series. Hence it has been suggested that the name Dubrajpur be replaced by Intertrappean Raj. mahal beds for beds overlying the Lower Gondwana sedim~nts. Beds, hitherto mapped as Dubrajpurs and 1I0W shown to contain Glossopteris and Vuttbraria should be included in the Lower Gondwanas. 2.1.4 Si"grauli Coalfied A new genus, viz., Alatocarpus is instituted to contain certain large platyspermic ~eeds. The species Samaropsis jcJ,zlim.is Saksena, 1955 from the South Rewa basin is also transferred to A/atocmpus. The Singrauli material contains A. indicus sp. novo (the typP species) some specimens comparable to A. (Sama,op.Jis) johillensis (Saksena) comb. nov,) and A/aIJcQ!pUS sp. 11. i;) suggesled that Samaropsis piTICtjmbti \\'alkorn, 1928 may also belong to A/alocarpus. The occurrence of the seeds and associ• ated plants on the age of the beds is briefly discussed. 2.1.5 Jharia Coalfield Tbe wood genera Barakaroxylon Surange and Mai,by, 1962 and lrzdox)/on Surange and :t\1aithy, 1963 are merged as the central and the 4 ) peripheral secretory canals, which distinguish these two genera, have been found in one and the same specimen. On the basis of priority the genus Barakarox)'lo'l has been retained. A new species Baraka7oxylolf monocanalosum has been instituted. It is characteris~d by the prr'sence of a single, central canal in the pith as opposed to B. }hariense which is characterised by a central canal and a number of peripheral canals. 2.1.6 Giridih Coalfield Four new species of fossil plants, viz , Gangamopteris oblancaolata sp. novo Euryphyllum olJovalum sp. nov., Dolianilia karharbJrensis sp. novo Buriadia /lorinii sp. novo have been recorded from the Karharbari beds of the Giridih Coalfield. 2.2 Sporae Dispersae 2.2.1 South Karanpura A systematic study of two miospore assemblages, one is from the shales associated with the Argada 'S' Seam, and the other is from another shale about 70 feet above the Argada IS' Seam, indicates that both the assemblages are palynologically more closely related to the Karharbari stage. 2.2.2 Johilla Coalfi'd A miospore assemblage containing 23 genera and 42 species from the Ganjra NalJa bt.ds is described. The genera Rugasaccites, Pach)saceus, Gondwanopollis and Rimospora are newly instituted. The stratigraphical position of the Ganjra Nalla beds is discussed in the light of the plant micro-and macrofossil evidences. 2.2.3 Dallongall) Coalfield On the basis of plant mt=gafo~siJs and the miospores recovered from the coal bearing beds the stratigraphical tosition of these beds in the Lower Gondwana succe~sion is discussed. 2.2.4 Jayanti Coalfield Miospore assemblages have been recorded for the first time from the matrix of two intercalated Talchir Boulder Beds.

These samples were tested for Chemical analysis, Crossing Point Temperature (CPT), Petrography, Infrared studies (IR) and Differential Thermal Analysis (DTA). All the test results vindicated that the aforesaid parameters had a definite relationship with the stratigraphic disposition or the ranks of coal. The low rank coals found as younger seams in the stratigraphic sequence were more prone to spontaneous combustion whereas the higher rank coals found at the bottom of stratigraphic se- quence were less prone to spontaneous combustion. Through combustibility characterisation by different tests, it was found that the upper Duman and Kaperti seams placed as younger seams in the stratigraphic se- quence are highly prone to spontaneous combustion whereas the lower Karakoh and Sonawani seams seem to be least prone to spontaneous combustion.

  • Brick Making from Over Burden Dump, a Mine Waste
    ISSN: 2455-2631 © August 2019 IJSDR | Volume 4, Issue 8 Brick Making From Over Burden Dump, a Mine Waste 1Navneet Nunar, 2A.K.Gautam 1M.Tech Student, 2Assistant Professor Maharishi University of Information Technology, Lucknow Abstract: Mineral waste utilization as a construction material for making building bricks and blocks has already started in developed and developing countries. In India, marble slurry, tailings and red mud are being suggested to use as a building material. Utilization of mine spoil for constructional bricks and blocks will generate additional employment during and after mine operation. Waste rock utilization in coal mining area reduce environmental impact, more availability of land resource and reduction in mining cost, which occurs on the maintenance of mine spoil as reclamation, plantation, slope stability etc. The plantation will be more effective and cheap in plain land than unstable sloppy dumps. Utilization of mine spoil for manufacture of constructional bricks will also conserve precious soil used in making clay bricks. Keywords: Over Burden Dump, Mine, Waste, coal Introduction- Coal is a very important resource for India where most of the industries such as thermal power plant, mineral industries are using coal for extracting energy. Around the world, India dominates the third position in the largest production of coal and has the fourth largest coal reserves approx. (197 Billion Tons). It has been estimated that 75% of India’s total installed power is thermal of which the share of coal is about 90%. Nearly about 600 Million tons of coal is produced worldwide every year. Coal based thermal power plant has consumed about 640 million tons of coal in 2015-16 which is about three fourth of the total coal consumed in the country.

  • Predicting Drainage Quality for Sustainable Exploitation of Coal
    Journal of Scientific & Industrial Research Vol. 63, November 2004, pp 919-926 Predicting drainage quality for sustainable exploitation of coal S Siddharth *, A Jamal, R K Tiwary ** and B B Dhar *** Central Mining Research Institute, Dhanbad 826 001 Received 11 May 2004; accepted 02 July 2004 In this paper, a technique has been suggested to know the quality of mine drainage even before the start of mining operation. The coal and associated rock samples are collected from the mine site. The mineralogical composition and geo- chemical character of each rock types occurring at the site are determined. The geo-chemical properties are measured in terms of R-pH, pollution production potential (PPP) and acid neutralization potential (ANP). The geo-chemical characteristics of various rock types indicate that they have different geo-chemical properties. There is a discrepancy in pH values obtained under laboratory conditions and field data and an explanation is given. On the basis of geo-chemical properties and weathering tests, it is found that except sandstone, all other litho-types such as, coal, shale, and shaly coal have the potential to deteriorate water quality and whatever the water pollutants present in the mine water are just because of interaction of these rock units with water. It is predicted that drainage from coal, shale, and shaly coal may be acidic, whereas drainage from sandstone is basic. The more or less same patterns are observed in the field. The technique suggested for the prediction of drainage quality may prove helpful and can identify rock types likely to produce water contaminants during their exposure to atmosphere in a mine.

Dr. Sarwar Rais Associate Professor, Department of Geology, Aligarh Muslim University Aligarh India. ABSTRACT The Talchir Formation (Permo-carboniferous) is the lowermost unit of Gondwana Supergroup which rests unconformably over the Precambrian basement of Indian peninsula. Modal analysis and geochemistry of Tal- chir sandstones and shales of Chirimiri area, Son valley sub basin, Chhattisgarh, is carried out to know nature of provenance and its composition, weathering condition and tectonic setting of both source area and depositional basin. These characters are determined with the help of QtFL parameter, and bivariate plot between TiO2 vs Zr, geochemical proxies [A/ACNK)*100] and ratio of major oxide K2O/Na2O vs SiO2 have been utilised to achieve this aim. The petrochemical attributes of the clastic rocks of Talchir Formation sug- gest that these sediments have been derived from continental block having rocks of mixed composition which was subjected to moder- ate weathering during late Palaeozoic time. These sediments were deposited in basin situated at passive margin. Introduction 1 presents the stratigraphic succession of Talchir Formation in Synthesis of compositional and textural properties of sediments Chirimiri area. and information from other lines of evidence help in interpret- ing the characters of source area (Pettijohn, F.

(Received 09 December 2004; revised version accepted 16 August 2005) ABSTRACT Ram-Awatar, Kumar M and Prakash N 2005. Palynological analysis of Lower Gondwana sediments exposed along the Umrar River, South Rewa Basin, Madhya Pradesh, India. Palaeobotanist 54: 87-97. The palynflora and other organic content in carbon?ceous shales, exposed along Umrar River, District Umaria have been studied. The organic matter comprises rich black debris, biodegraded, amorphous and structured material, mainly composed ofland-derived plant fragments, e.g., leaf cuticles, twigs, stem (elements with bordered pits, xylem and phloem tissues) and roots with their various degradational phases. The basal part ofthe sequence indicates reducing environment ofdeposition while upper part denotes a slow depositional setting under moderately oxidizing conditions. Two palynozones have been recognized: the basal-most sequence is characterized by the dominance ofCa{{umispora and Jayal1lisporiles, wh iIe the younger sequence is dominated by Parasacciles-Plicalipo{{enites and zonate triletes in association with striate-bisaccate pollen affiliated to the Lower and Upper Karharbari miofloras. Record of Dictyotidium, Muraticava, Leiosphaeridia, Ba{l1Iee{{a, Foveofilsa and Tetraporil1a suggests a brackish water regime during deposition of these sediments. The present study deals with the age of spores-pollen assemblages and the characteristics of organic matter in order to assess the depositional environment of lithologically undifferentiated, coal­ bearing Early Permian strata of South Rewa Basin, Madhya Pradesh.

    INDIAN COALS FOR SPONGE IRON PROCESS s. BAGCH1, K. K. RAYCHAUDHURI K. RAJA Central Fuel Research Institute, P.O. FRI. Dist. Dhanbad, Bihar Abstract IN CONTRAST to conventional two stage process of steel making via blast furnace, direct steel making with pre-reduced iron ores or agglomerates have attra cted attention in recent times. This is particularly so for dev?loping countries where there is availability of other raw mate- rials for iron making but there is dearth of or limited resources of coking coal and abundant supply of other type of non coking coals. In terms of energy equivalent, availability of . solid fuel is many hundred times more than that of natural gas. Extensive attempts have therefore been made to utilise non coking coals to produce iron by non conventional methods such as direct reduction processes. The solid iron produced by reduction technique known as 'sponge' can then be transformed into steel by melting. An attempt has been made in the paper to indicate the available resources of Indian coals, their nature and property which may be considered suitable for the production of sponge i ron either as such or after beneficiation. Indications have also been given for the possibility of utilising char from the fluid bed car- bonisation of non coking coal where such material can be obtained from an integrated formed coke plant. Introduction temperature, oxygen content of the blast, humidification of the blast and by high The Conventional two-stages process top pressure of the blast furnace. of steel making via blast furnace has been in vogue over a century.

In these cases, the fires have occurred in most of these opencast mines causing loss of the coal reserve, production, productivity and safety. In this research work, 13 such mines have been studied over a period of three years and critical para- meters for occurrence of these fires have been identified. This paper presents the details of observations for two such mines and detailed statistical analyses have been carried out by using confidence interval (C.I.) and analysis of variance (ANOVA-Two-way classification) for finding out the range of these critical parameters which can be controlled to reduce the occurrence of these fires. Keywords: Opencast over underground bord and pillars, critical to fire, mining parameters, critical review, mine operational parameters, confidence interval (C.I.) and analysis of variance W wielu kopalniach odkrywkowych w Indiach wydobycie prowadzi się w wyrobiskach ponad filara- mi ochronnymi udostępnianymi przy wykorzystaniu metody filarowo-komorowej. W takich warunkach powstające często w kopalniach pożary powodują utratę zasobów węglowych, zmniejszenie wydajności i poziomu wydobycia oraz negatywnie wpływają na bezpieczeństwo pracy.
